AS4593 RELIANCE
Unclassified ARIN
Summary
ABB Motors and Mechanical Inc.
enterprise legacy
AS4593 (RELIANCE) is held by ABB Motors and Mechanical Inc., ABB's US motors and generators business, headquartered in Fort Smith, Arkansas. The handle comes from the Reliance Electric brand, which lives on in ABB's Baldor-Reliance motor line.
What it's used for
Industrial enterprise networking. The address space serves the company's offices, plants and corporate systems across its US manufacturing footprint.
Notable
- The handle traces a long ownership chain: the Reliance Electric name passed into Baldor Electric, ABB acquired Baldor in 2011, and the US entity was renamed ABB Motors and Mechanical in 2018. The AS handle never changed.
- A good reminder that a handle identifies a record, not a company. Confirm the current holder before reading anything into the name.

Classification and threat
Unclassified Not in the curated lists. Most of the ~80,000 allocated ASNs are not.
Spamhaus DROP
Not on ASN-DROP The network as a whole is not listed.
No DROP prefixes None of its announced space is on the DROP prefix list.
Spamhaus DROP ("Don't Route Or Peer") lists space and networks run by, or hijacked for, spam and cybercrime operations: 446 networks and 1,852 prefixes, as published 2026-10-27. A short, high-confidence list, so a match is worth taking seriously, and absence from it says little on its own.
FBI IC3
No IC3 indicators Nothing from the FBI IC3 feed.
IC3 threat data is alpha. Absence of an indicator is not evidence of good behaviour, only of absence from this one feed.
